Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
Electrolysis of water is a chemical change. Exposing sodium chloride to sunlight would cause some heating, but no chemical changes.
Is the energy to power a computer called Chemical energy?
No, the energy that powers a computer is electrical energy. Chemical energy is energy that is stored in the bonds of molecules. Batteries, candles, matches and food are some things that have chemical energy. When the molecules/compounds' bonds are broken, the chemical energy is released. In a candle, this would cause a small fire. Electrical energy is the movement of electrons. The electrons move quickly inside the wire, & power the computer as electricity.
Why aren't chemical additives good for us?
A good deal of additives cause isotopes in your body called 'free radicals'. These isotopes can cause some very dangerous disorders, including cancer.
What are the chemical properties of glue?
There are plenty of different glues, and pretty much they only have two things in common:they have a certain mechanical strengththey stick to stuffApart from that, they can be just about anything. Some harden by evaporation, some through a chemical change, some (like hot glue) through a physical change.
Why do people burn coal and oil?
Heat can cause some matter to burn. Burning is a chemical change. When fuel burns, the energy stored inside it is released.
What type of weathering causes acid rain?
carbonation is an example of chemical weathering carbonation is an example of chemical weathering
What is the type of weathering that involes a chemical change in some of the minerals in a rock?
Chemical weathering
Is erosion chemical weathering?
No. Erosion usually involves the transportation of material from one place to another place. Chemical weathering involves the reaction of natural Earth materials with acidic fluids, causing dissolution.
What are some things that can cause weathering?
Some are water,ice,and plant growth your welcome ☺❤
What are the different types of weathers?
Mechanical weathering, Biological weathering and Chemical weathering.
Can you give me some notes about weathering?
There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.
Animal burrows dug in rock that let in water and air chemical or mechanical?
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
Some agents for chemical weathering?
OxygenFreezing and thawing

Acid rain
What are some agents of chemical weathering?
Water is one

What is it called when rocks break down without changing in chemical composition chemical weathering oxidation leaching or mechanical weathering?
The only one from the list above that does not involve some form of chemical change is mechanical weathering.
